Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
The neutrons in an atom have the least amount of mass?
No actually, the neutrons and the protons of an atom are relatively the same in mass. Electrons have the smallest mass in an atom, and are not even considered when we look at the mas sof an atom.
How do you find the mass number given the proton electrons and atomic number but not the neutrons?
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
How is electrons and mass number related?
it isn't - the number of electrons in an atom will be the same as the proton number of that atom, but the mass of an atom includes the number of neutrons, and in every stable element heavier than hydrogen, the number of neutrons is the same as or greater than the number of protons. Also, the mass will vary between isotopes of the same element, which will contain the same number of protons and hence electrons but a different number of neutrons. Generally, in stable nuclei, as the number of electrons in an atom in creases, the mass increases as well, but these are not directly linked as to be stable, heavier nuclei require a greater proportion of neutrons in the nuclei so will have a greater mass to electron number ratio
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
The mass of neutrons and electrons are about the same?
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.
Do protons nuetrons and electrons all have about the same mass?
Protons and neutrons have about the same mass, but electrons are much, much lighter.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.

Neutrons and what almost have the same mass?
A neutron and a proton almost have the same mass. A neutron and 1,840 electrons almost have the same mass.
How do you find the mass number given the proton electrons and atomic number but not the neutrons?
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.

What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
What determines the mas of an atom?
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
